I have a new Surly Disk Trucker that I think may need an adjustment. When the front disk brake is engaged, the front wheel can still rock slightly (but noticeably) forward and backwards. I am sure the disk is not slipping and it seems to be movement in the hub. Does this require an adjustment? Any idea what the problem might be? Thanks for any ideas!

it could be loose but make sure the headset is not at fault too.
you will need cone wrenches to tighten. if it is the axle you should be able to detect it by wiggling also
